Gastrin-releasing peptide receptor expression in gastrointestinal stromal tumours [PDF]

ESMO Gastrointestinal Oncology
Background: There are limited treatment options for patients with advanced or metastatic gastrointestinal stromal tumours (GISTs) that lack mutations targetable by tyrosine kinase inhibitors (TKIs) or that have developed resistance to TKIs.

Preclinical Characterization of a Stabilized Gastrin-Releasing Peptide Receptor Antagonist for Targeted Cancer Theranostics [PDF]

Biomolecules, 2023
Radiolabeled gastrin-releasing peptide receptor (GRPR) antagonists have shown great promise for the theranostics of prostate cancer; however, their suboptimal metabolic stability leaves room for improvements. It was recently shown that the replacement of

Neuropeptide gastrin-releasing peptide induces PI3K/reactive oxygen species–dependent migration in lung adenocarcinoma cells

Tumor Biology, 2017
Nerve fibers and neurotransmitters have increasingly been shown to have a role in tumor progression. Gastrin-releasing peptide is a neuropeptide linked to tumor aggressiveness, acting as an autocrine tumor growth factor by binding to its receptor ...
